摘要

在本文中，我们发现从红树林Avicennia marina根中分离的Talaromyces stipitatus作为内生菌，产生耐盐几丁质酶和壳聚糖酶。内生菌耐盐，即使在生长培养基中存在高浓度NaCl的情况下也能产生这些几丁质修饰酶。所产生的壳聚糖酶可作用于低、中、高乙酰化程度的壳聚糖。NaCl的存在影响内生菌产生几丁质酶和壳聚糖酶的异构体。几丁质酶活性不受NaCl浓度的影响。

Salt-tolerant chitin and chitosan modifying enzymes from Talaromyces stipitatus, a mangrove endophyte

In this paper, we show that a Talaromyces stipitatus isolated as an endophyte from the root of the mangrove tree Avicennia marina, produces salt-tolerant chitinase and chitosanases. The endophyte is halotolerant and produces these chitin modifying enzymes even in the presence of a high concentration of NaCl in the growth medium. The chitosanases produced could act on chitosans of low, medium and high degrees of acetylation. The presence of NaCl influenced the production of isoforms of chitinase and chitosanase by the endophyte. The chitinase activity was not altered much by NaCl concentration.
